This report describes the translation of formal speciications of container classes to passive test oracles. Speciically, we use Object-Z for speciications and C++ for oracles. We discuss several practical issues for the use of formal speciications in test oracle generation. We then present the translation process for three passive oracle models and evaluate how each model satisses our goals of ...

The main concepts of ZimOO are illustrated by a small case study, a speciication of a protected cooker. ZimOO is an extended subset of Object-Z and allows descriptions of discrete and continuous features of systems in a common formalism.

This paper presents a logic for Object-Z which extends W, the logic for Z adopted as the basis of the deductive system in the Z Base Standard. The logic provides a basis on which tool support for reasoning about Object-Z speciications can be developed. It also formalises the intended meaning of Object-Z constructs and hence provides an abstract, axiomatic semantics of the language.

in this paper‎, ‎we consider a general integral operator $g_n(z).$ the main object of the present paper is to study some properties of this integral operator on the classes $mathcal{s}^{*}(alpha),$ $mathcal{k}(alpha),$ $mathcal{m}(beta),$ $mathcal{n}(beta)$ and $mathcal{kd}(mu,beta).$‎

UML, and other object-oriented approaches to system specification and design, are increasingly popular in industry. Many attempts have been made to formalise either the notations, the system models produced using these notations, or both. However, there have been no attempts to compare the expressiveness of the formal approaches. This paper compares Z and Object-Z approaches to object-oriented ...

Patterns provide an informal approach to the design of software. However patterns are compatible with more formal techniques for speciication. In this paper we describe a set of patterns for developing object-oriented software designs for user-interfaces and show how these patterns can be applied using Object-Z speciications as a guide. Collectively the patterns generate an interactor-based arc...

This paper presents a method of formally specifying concurrent systems which uses the object-oriented state-based speciication language Object-Z together with the process algebra CSP. Object-Z provides a convenient way of modelling complex data structures needed to deene the component processes of such systems, and CSP enables the concise speciication of process interactions. The basis of the i...

A notation is presented for formally describing the design of a user-interface. The speciication of a system is given using the Object-Z formal speciication language and then extended to describe presentation using an Object-Z class library. The Object-Z notation is extended to enable designs to be described using UAN (User Action Notation) annotations and the semantics for the design extension...
